SPECK-REMOVER.

$pecification of Letters Patent.

Patented July 8, 1919.

Application filed January 3, 1919. Serial No. 269,471.

T 0 all whom it may concern:

Be it known that 1, WILLIAM F. Moon, a citizen of the United States, andresident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented new and useful Improvements in Speck-Removers,of which the following is a description, reference being had to theaccompanying drawings, which are a part of this specification.

The invention relates to a device for removing lumps of fiber or whatare commonly called specks from yarn or thread, previous to its use in aspinning or weaving machine, and is fully described in the specificationv and shown in the accompanying drawing in which:

Figure 1 is a bottom plan view of the machine embodying the invention;Fig. 2 is a section taken on the line 2-2 of Fig. 1; Fig. 3 is a detailtop plan view of the machine; Fig. 4 is a section taken on the line 4L1of Fig. 3; Fig. 5 is a detail view similar to Fig. 2 showing a modifiedform of construction; Fig. 6 is a section taken on the line 6 6 of Fig.5.

In the drawings, the numeral 5 designates generally the frame of themachine, 6 a drive shaft mounted in said frame and provided with apulley 7 driven from any suitable source of power, and 8 a driven shaftmounted in the frame and carrying a bevel gear 9 meshing with a bevelgear 10 on the shaft 6.

In the drawings I have shown a plurality of speck removing devices, eachof which successively acts upon the thread to remove any speckstherefrom so that if the first device does not remove the speck it willbe removed by another of the devices.

Each of these speck remover devices is mounted upon side frame members11 and consists generally in means for presenting the speck in positionin which it may be readily severed from the thread or yarn by thecutters or shears hereinafter described.

The means for presenting the speck in position for removal consists of apair of guide plates 12 and 13 which are slightly spaced apart to form aslit 14L, andineans for turning the thread so that when it passesthrough the slit the speck on the thread will be presented below theslit. This means consists of a pair of sector shaped blocks 15 which areyieldingly held together and against the plates 12 and 13 by means ofsprings 16, each having one end disposed in a radial slot 17 in eachblock and the other end disposed in a radial slot 18 in one of thespaced frame members 19. The pressure of the blocks upon the plates maybe regulated by varying the pressure of the springs against the blocksby means of adjustable screws 20 hearing against the ends of the springsin the slots 18 of the member 19. The blocks meet each other at theirlower ends 21, but are separated at their upper ends 22 so that thethread or yarn may be readily threaded into the slit lt by passing saidthread down between the space between the member 19 and between theyieldingly mounted blocks 15. is turned by means of beveled portions onthe ends of the blocks which, whenthe thread advances, deflects thespeck on the thread downwardly, thereby turning or twisting the threadwhich brings the speck below the level of the plates 12 and 13. When thespeck is thus brought down below the slit it is severed from the threadby means of a reciprocating cutter 2a, or a rotary cutter at whichcoacts with the plate 12 to shear or cut the speck off from thetraveling thread as the cutter 2+1 or 2 1 is spaced slightly away fromthe plate 13, but slides on plate 12.

The cutter 2 1 for each device is adjustably secured to a slide block 25movable in a guide notch 26 in one of the members 11 and upon a framestrip 27. Each block 25 is reciprocated back and forth by means of aneccentric link 28 which is pivotally connected at one end to the blockand mounted at its other end upon an eccentric 29 on the shaft 8. Theeccentrics for the different devices are set at different crank angleson 9 the shaft so that the cutters 21 of the dif ferent devices willoperate at different times so that should a speck pass through the firstdevice or devices when the cutter is on its return movement it will besevered by the cutter of the next device which is on its forwardmovement.

The cutter 2 1 is a rotary knife mounted on a shaft 30 carrying a bevelgear 31 meshing with a bevel gear 32 mounted on a shaft 33 and a seriesof the devices provided with the cutters 2% may be provided in whichinstance all the shafts like the shaft 33 may be connected up to acommon drive shaft.

The plates 13 are adjustably secured to The thread.

the frame by screws 13' and the cutters 2a are adjustably secured to theblocks 25 by screws 25.

It will be understood that any changes in the precise embodiment of theherein disclosed invention may be made as come Within the scope of theclaims.

What I claim as my invention is:

1. In a yarn speck remover, the co1nbination of means for guiding thethread, means for turning the thread to bring the speck below the guidemeans, and means for cutting the speck from the thread as it advancesthrough the guide means.

2. In a yarn speck remover, the combination of a pair of spaced apartplates and a support for the thread beneath the plates, means forturning the thread as it advances between the plates to present thespeck below the plates, and means for severing the speck thus presentedfrom the thread.

3. In a yarn speck remover, the combination, of a pair of plates spacedapart to form a guide slit, a support adjacent the plates having abeveled notch in line with the slit and adapted to be engaged by thespeck on the advancing thread for turning the thread to present thespeck below the guide slit, and means for severing the speck thuspresented from the thread.

et. In a yarn speck remover, the combination of a frame, means forguiding the thread, a pair of yieldingly mounted blocks in said frameadjacent said guiding means for bringing the speck below the guidemeans, and means for cutting the exposed speck from the advancingthread.

5. A plurality of devices as specified in claim 1 to successively actupon the advancing thread.

6. In a yarn speck remover, the combination, of a pair of plates spacedapart to form a guide slit, a pair of yieldingly mounted thread supportsadjacent said plates and having registering beveled corners to form anotch in line with the slit and adapted to be engaged by the speck onthe advancing thread to turn the speck for cutting, and means forcutting the speck from the thread.

In testimony whereof I aflix my signature.

YVILLIAM F. MOON.
